Dimethylethanolamine (DMAE or DMEA) is an organic compound with the formula (CH₃)₂NCH₂CH₂OH. It is bifunctional, containing both a tertiary amine and primary alcohol functional groups. It is a colorless viscous liquid. It is used in skin care products for improving skin tone and also taken orally as a nootropic. It is prepared by the ethoxylation of dimethylamine.
